Description

Inpeller of self-priming pump

제1도는 본 고안의 일부절개한 분해사시도.1 is an exploded perspective view partially cut out of the present invention.

제2도는 본 고안의 조립단면도.2 is an assembled cross-sectional view of the present invention.

제3a, b도는 종래 인펠러의 요부 분해사시도.3a and 3b are exploded perspective views of main parts of a conventional infeller.

본 고안은 자흡식 펌프에 사용되는 공기흡입용 인펠러에 관한 것으로 인펠러 측판과 본체를 합성수지제로 구성하되 측판의 내면에는 흡인익편의 형상을 요설하고 그 외주연단부에 착공부를 뚫으며 본체의 내면에는 흡인 익편을 돌설하고 착공부와 연통되도록 핀체를 돌설시켜 되는 것이다.The present invention relates to an air intake infeller used in a self-priming pump, wherein the ineller side plate and the main body are made of synthetic resin, but the inner surface of the side plate outlines the shape of the suction blade, and drills the hole at the outer periphery of the main body. There is a protrusion of the suction blade and the pin body so as to communicate with the cavities.

종래에도 첨부도면 제3도에서 보는 바와 같이 본체와 덮개판에 여러개의 구멍 (a)을 뚫어 별도의 괘착돌기(4a)와 괘착판(4a)을 관착시켜 그 단부를 용착시켜 되는 것이 있었으나 이와같은 것은 본체와 덮개판에 여러개의 구멍을 뚫거나 장공(b) 및 장홈(b')을 뚫어야 했으므로 인펠러 자체의 강도가 약화되어 인펠러의 구조가 견고치 못했으며 그 제작 및 가공이 까다로웠으며 제작 생산비도 고가였던 것이다.Conventionally, as shown in FIG. 3, a plurality of holes (a) are drilled in the main body and the cover plate to weld separate end projections 4a and the seating plate 4a to weld the ends thereof. It was necessary to drill several holes in the main body and the cover plate, or to drill the long holes (b) and the long grooves (b '), so that the strength of the inpeller itself was weakened, so that the structure of the inpeller was not solid and the manufacturing and processing was difficult. Production costs were also high.

본 고안은 상기한 문제점을 감안하여 고안된 것으로 핀체를 본체의 흡인익편과 일체로 성형하고 측판에 흡인익편 삽입용 요함부를 요설하여 견고히 조립되게 하므로서 하나의 핀체에 의해서도 견고히 조립할 수있게 함에 그 목적이 있다.The present invention was devised in view of the above-mentioned problems, and the object of the present invention is to form a fin body integrally with the suction blade piece of the main body and to assemble the pinnacle for inserting the suction blade piece on the side plate so that it can be firmly assembled by a single pin body. .

본 고안의 내용을 첨부된 예시도면에 의하여 상세히 설명하면 다음과 같다. 즉 합성수지제로된 인펠러 본체(1)와 측판(2)을 접합착설함에 있어서, 인펠러 본체(1)의 내면에 형성한 요함부(3)와 착공부(4)에 측판(2)의 내면에 형성된 흡인익편(3a) 및 핀체(4a)가 끼워진 그 단부(4b)를 용착하여서 되는 자흡식 펌프의 인펠러이다.When described in detail by the accompanying drawings the contents of the subject innovation as follows. That is, in joining and installing the infeller body 1 and the side plate 2 made of synthetic resin, the inner surface of the side plate 2 is formed in the recess 3 and the hole 4 formed on the inner surface of the infeller body 1. It is an infeller of the self-priming pump formed by welding the end 4b in which the suction blade piece 3a and the pin body 4a which were formed in it were welded.

첨부도면중 미설명부호 5는 흡입공, 6은 회전축 축수부를 표시한다.In the accompanying drawings, reference numeral 5 denotes a suction hole, and 6 denotes a shaft bearing part.

본 고안의 인펠러는 그 중량이 가볍고 조립제작이 용이하여 염가로 제공받게 된다. 특히 본 고안의 조립제작에 있어서 측판(2)에 요설된 요함부(3)내에 접착제를 발라 흡이익편(3a)이 접착되게 하고 본체(1)의 내면에 돌설시킨 흡인익편(3a)의 외주연단의 핀체(4a)가 측판(2)의 착공부(4)에 끼워지게 조립한 다음 동 핀체(4a)의 단부(4b)를 가열 용착시키면 간단히 조립제작되는 것이다.The inpeller of the present invention is light in weight and easy to manufacture and is provided at low cost. In particular, in the fabrication of the present invention, an adhesive is applied to the recesses 3 provided on the side plate 2 so that the suction piece 3a is bonded to the outer periphery of the suction blade piece 3a which is inclined to the inner surface of the main body 1. When the end fin body 4a is assembled so as to be fitted to the hole 4 of the side plate 2, and then the end portion 4b of the fin body 4a is heat-welded, it is simply assembled.

이와같은 본 고안은 측판에 요설된 요함부에 흡인익편이 삽입되게 한후 흡인익편에 일체로 성형된 핀체가 측판의 착공부에 관착시킨후 측판의 외주면에 노출된 핀체의 선단부만을 가열용착시키면 요동되지 않고 견고하게 조립되므로 제작이 용이하고 그 조립이 간편하여 염가로 제공받게 되는 것이다.The present invention is such that the suction blade is inserted into the recessed portion of the side plate, and the pin body integrally formed on the suction blade is welded to the hole of the side plate, and only the tip of the pin body exposed to the outer circumferential surface of the side plate is not shaken. Because it is firmly assembled without being easy to manufacture and its assembly is simple, it will be provided at a low cost.

Claims

In joining and installing the infeller body 1 and the side plate 2, suction is formed on the inner surface of the side plate 2 in addition to the recess 3 and the hole 4 formed on the inner surface of the infeller body 1. An infeller of a self-priming pump formed by welding the blade piece 3a and the end portion 4b into which the fin body 4a is fitted.
